The Omega was the first Electra to carry the 5-way tone spectrum knob designed by Tom Presley that would later become a trademark of the MPC guitars. Headstock was open-book shape in 76 and fan shape for all other years. In 1982 the X110 was redesigned with a slightly different body shape:

Like most Electras with a fan-shaped headstock, the Omega is believed to be made by Matsumoku.

The X110 is one of a very few cases of confusion where the same model number was applied to two different guitars: X110PW and X110NA were single-pickup versions of the Electra Phoenix, a bolt-neck double cutaway quite unlike the rock strad.

With maple neck and brass nut, these models resemble LP copies in appearance but are quite different to play- much more reminiscent of original humbucker-guitar designs of the 80's.

Because this model straddles the transition period away from 'lawsuit era' copies, its changes in headstock shape and truss rod cover are an interesting study. All early (non-fan shape) models carry Hoshino-style serial numbers, in which the first digit is month and the next two are year. This suggests that these Zephyrs were made by either Matsumoku or Fujigen, both of whom made guitars for Hoshino. Later fan-shaped models are assumed to be made by Matsumoku.
